A Titanium Sapphire laser is passively mode-locked with the use of an external cavity containing a nonlinear medium. No active modulation of the laser gain or loss is required for ultrashort pulse generation. The mode-locked output is a continuous train of chirped 2 ps pulses which may be dispersively compensated with a grating pair of obtain 560 fs pulses. For comparison purposes, the Ti:Al{sub 2}O{sub 3} laser is actively mode-locked to obtain 60 ps pulses, and the pulses are shortened using the nonlinear external cavity to obtain chirped 2 ps pulses.
